I guarantee you it is not clipping when the OPPO Picture Adjustment settings are all set at their factory default (0) values.

The Dynamic Range High chart on Spears & Munsil shows separate, blinking bars for each individual Luma value from just below Reference White, through Reference White, and through the entire range of Peak Whites if the Display is able to reproduce those. On the 103, they are *ALL* distinguishable from the maximum Luma value (the bright white background of the chart) on a Display that can reproduce those, regardless of whether you are using YCbCr 4:4:4, YCbCr 4:2:2, or RGB Video Level output format.

The output is identical to that of other players known to properly pass Peak Whites -- e.g., the PS3 when set to YCbCr 4:4:4 with SuperWhite enabled.

In addition, OPPO has digital HDMI data captures of the output stream (part of their engineering bench testing) which show the high Luma values all being passed correctly -- a test which is, of course, independent of what any given AVR or Display might do with that output.

He also mentioned the White was not clipping but the CMS was/is above IRE90.
So lowering the contrast value on the Oppo was not to prevent the Oppo from clipping the White (because the Oppo is not doing that) but to prevent the Oppo from clipping the CMS above the IRE90 range.

^ Again, the HDMI digital data captures OPPO has done show this not to be the case. They run files with specific pixel values (Luma and the 2 Color Differences) through the player and capture the digital output stream (no AVR or Display involved) to make sure those values are not being altered (clipped). This is part of the Q/A of Dithering, for example, which imposes small, random differences by design, so you need to check that the differences are of the intended size and only occurring when they are supposed to be occurring.

It's always possible that a bug has crept in of course since the last time they checked that, but rendering bugs are usually not that subtle.

My apparent HDMI handshake (with loss of audio on HDMI 2 and video resolution/format difficulties) issue has now become apparently uncorrectable. Reseating HDMI plugs no longer corrects the issue. I completely removed and re-inserted every HDMI plug on every device. I also end swapped the cable from HDMI 2 to my receiver, as well as attempting to use a different HDMI input on the receiver. I also looked at both ends of the HDMI cables and the HDMI receptacles on the Oppo, and the AVR, and cannot see that there are any bent pins, or any visible damage. The HDMI cables being used are the ones provided by Oppo.

This issue began soon after the installation of the current firmware and has become more and more consistent and resistant to correction since. Is anyone else using a split A/V setup with a Pioneer Elite SC-77 (or other similar Pioneer AVR)?

After further experimentation and process of elimination, this appears to be an HDMI cable failure. After 2 months it is finally continuous and is duplicatable wherever the cable is moved to. I'm liking HDMI less and less.

I just checked this again in my setup with my test 103, and I don't see any such clipping.

Tested with Spears & Munsil v2, Blu-ray > Advanced Video > Setup. In this section of this calibration disc there are 6 charts that display the high Luma end of the video data. These are Contrast Y (i.e., Luma), Contrast Cb, Contrast Cr, Contrast Red, Contrast Green, and Contrast Blue.

All 6 display the given data channel as individual, labeled bars for Luma 231 through 253 against a background of Luma 254. There's also a double ramp used to check for quantization (rounding) errors.

(For newbies: Reference White has a Luma value of 235, and of course no color. The Luma values from 236 to 254 are the Peak White values. 255 is a reserved value. The pixel data on disc is in YCbCr format where the Y component is the Luma or gray scale brightness of the pixel, and the Cb and Cr components are the Blue and Red "color difference" values describing how much blue/red to add or subtract to that gray scale brightness to color the pixel. E.g., take all the Blue and Red out of a white pixel and you end up with a Green pixel. YCbCr format can be converted to RGB format -- Red, Green, and Blue component values for each pixel. A gray pixel anywhere in the range from Black to White would then be a pixel that has equal values for R, G, and B.)

In all 6 charts, I can see the data bars up to 253, which is correct. Of course the bars near 253 are tougher to see as they are closer to blending into the Luma 254 background. Check this in a darkened room with eyes adapted. So: No clipping in either whites or colors.

The 103 is running the Official 0515 firmware. I'm using HDMI 1, set to output 1080p/24 using YCbCr 4:4:4 and Deep Color OFF (Dithered). The Dithering in the player is needed for the way I use my Display.

NOTE: All this really proves is that the individual values up there really are present on the HDMI cable -- i.e., the OPPO is not clipping, say, values above 245 to 245. The Gamma of these high Luma values may or may not be correct. But that's a Display calibration issue, not an issue with the output of the OPPO.

------------------------------------------

Now, it is not at all unusual for *A DISPLAY* to clip one or more color channels at high Luma. For example, the Display might be able to show Blue distinguishable up to only Luma 245, even though Red and Green don't clip. One symptom of this is that high Luma value White bars start to develop a color tinge because, in this example, the Blue is only going up so high.

The way to check if THIS is the problem is to reduce white levels (i.e., using the Contrast control) in the Display (*NOT* in the OPPO). The higher Luma value bars should start to become visible -- which also demonstrates that the player itself is not doing the clipping, because those bars are there, on the HDMI Cable, to view if only the Display could handle them.

In such displays, there's a trade off that has to be made for the Display's own Contrast setting. Lowering the Display's Contrast setting lowers dynamic range (i.e., maximum image brightness). As long as there is no Clipping up to Reference White in any color channel you can live with that. If there is clipping (in the Display) above Reference White, you can lower the Display's Contrast setting to reduce that, but only so far as still leaves you with a pleasing appearance for Reference White -- i.e., not gray or dingy. This can be quantified in terms of recommended light level for Reference White (for your type of Display) if you use an optical sensor.

Having an HDMI cable fail on you is a right of passage. HDMI.ORG would probably describe it as a character builder.

Most likely the failure is internal to the cable -- a conductor break inside the insulation or a failed solder joint. However, do check for bent pins. Get a flashlight and check the plug ends and also the sockets. The reason is that a damaged plug can also damage the sockets it is plugged into.

Once you have replaced the cable and confirmed things really are fixed, don't forget to destroy the bad cable. You'd be amazed how common it is for people to mistakenly re-use cables they've previously proven are bad....

I tested mine using the same material last night. Also no clipping on Y, Cb, Cr, R, G, or B. YCbCr 4:4:4 with Deep Color set to 36 Bits. I use the 36 Bit setting to take advantage of the Bit Resolution Expansion (QDEO True Color Processing) feature of the Marvel QDEO Video processing on HDMI 1. I am easily able to detect the removal of banding on a full screen grayscale ramp as my display is capable of displaying greater than 24 bit video. I cannot however tell any difference between the 30 Bits and 36 Bits setting. Dithering apparently defeats the effects of this processing as both the dithered settings result in the ramps appearing identical to the 24 Bits setting, leaving the banding quite perceptible.

A simple failure wouldn't be so bad. 2 months of chasing a poltergeist is a PITA. Now it has finally reached the stage of being repeatable and duplicatable. I'm not sure how I'd ever be able to diagnose the real problem when some other action would apparently correct the issue. I have checked for bent pins. None to be found. I also end swapped the cable with no change in behavior as well as moving the cable to the other HDMI output on the Oppo, and a different HDMI input on the AVR, and the handshaking issue followed it. To eliminate the possibility that an HDMI handshaking issue had somehow otherwise developed between the 103 and my AVR, I used another HDMI cable between them, and it is working normally (so far).

I've contacted Oppo to see if the cable may be covered either under its own warranty, or under the 103's.

^ The failed cable is a 3 foot that I ordered from Oppo about 3 months after I ordered the 103 from them, so its not the one that came with the 103. The 6 foot cable that came with the 103 was being used directly from the 103 to the video display, but is now connected to the AVR temporarily (using the 103's HDMI 1 only) until the failed cable is replaced.

If you only use HDMI2 for audio (like me) you could also leave Color Space to "Auto".

All digital Displays need to dither at some point before the pixels light up to eliminate quantization artifacts. For most folks, that happens by default in their Display and they don't need to OPPO to do it. In my case, my display thinks it is being fed by a computer, and, as a side effect, apparently bypasses its own, internal dithering (i.e., it thinks dithering's already been done by the graphics device feeding it). So dithering in the OPPO is the bees knees.

For some displays, disabling their video "enhancement" processing -- almost always a good idea -- may also mean they don't dither. Again, dithering in the OPPO then becomes just the ticket.

I also have video enhancement processing OFF on the display.
How do I know or can I check if my display applies dither?

I've found that Ratatouille Chapter 10 scene I've talked bout many times now is good for testing this as well. If you need to apply dithering then the Color Space choices without dithering will show more of the structure in that night sky through lit fog frame. It's pretty obvious when Dithered is better in that case. If adding dithering does NOT improve that image then leave it off, as you don't want to be doing dithering twice.

Yes, HDMI2 only for Audio (SACD, DVD-Audio, CD, hi-res audio files, sometimes DVD -> once a year, atmos).

Auto or 4.4.4 (HDMI2) - both selections are fine; thx.

So the dithering "function button" in the Oppo 103 is the Deep Color (Off) selection?

Deep Color: Off (Dithered) ... Yep it is.

______________

* In my Rotel RCD-991 CD player there is a "Dither" function button on the front panel.
I can add various 'dither' levels to my music; depending of what's playing, and what sounds best to my ears.

{Every digital music player should have that, I think. ...Plus an asynchronous function too, like in the Oppo 105, for digital jitter reduction/elimination from its dedicated USB port.}

Next; Dolby Atmos from the Oppo 113 and 115 (up to 4 overhead "beds"). ...Sleep bedder @ night.
- Phase reverse switch? ...Why not, in them next Oppo players (2016).
...And a "Dithe"r adjustable level button selection (on the remote), for music listening. ...Tell Oppo that Bob.

Is there also something on Spears & Munsil II which is an indicator for dither?

You can try the various charts with color ramps. But quantization artifacts are tough to see because only thin lines will be different from what they should be.

HI all!


Just an update on my experience with the 103. After about 5 months of comparing the analogue out of the 103 into a Burson Soloist headphone amp, and comparing it to the Schiit Bifrost Uber DAC, I finally concluded that there is no audible difference. My final evaluation with a demo pair of Grado GS1000e headphones, which are brutally detailed, was the last straw. Volume matched, I could not tell one from the other.


This darn blu-ray player is something else!

Next, compare the analog stereo outs of the Oppo 103 perfectly volume matched with the analog outs of an Emotiva ERC-2 (or ERC-3) CD player, and playing through the exact same pair of loudspeakers and playing the exact same music recording(s).

* And to Daffie who doesn't have 'Ratatouille' on Blu-ray; go get it, it's a must have Blu-ray title.

^ I would agree about "RaRaToodie" as my son used to call it. An awesome movie!
Last night after the talk of dithering options, I decided to play my copy and double check my settings
to see if I still didn't need dithering (as if it had changed, but never hurts to double check).
I ended up watching half the movie of course. Good stuff.

I agree, use it to test it and there is a high chance that you might end up watching it entirely. ...Irresistable.

Hi Everyone

I am a total newbie on these boards but a proud owner of the 103. I don't know if this query is going to make any sense but I hope someone can advise.

I am using the Oppo without an external amp or speakers, so everything comes through the TV, which is rather feeble but O.K. for movies. Now, I can get decent sound if I plug in my headphones into the TV but I want to know if I can get better sound by connecting the phones into the Oppo when I play my CDs. I know there is no headphone input on the 103, but I do have a NuForce headphone amp, which has normal RCAs and coaxial connects.

Now, the thing is I can't figure out how to connect the NuForce properly to the Oppo to drive the 'phones. The front left and right don't work. The coaxial doesn't work. Can anyone let me know if I can get the headphones to work with the NuForce and which connects to .... connect?
